Due to the high nutritional value, appealing taste, and attractive color, the fruit juice of B. macrophylla has the potential to be developed as a functional beverage. The present study was conducted to determine the phytochemical profile of B. macrophylla fruit juice using GC-MS and LC-MS/MS. GC-MS analysis was performed with the Agilent Technologies 7890 Gas Chromatograph with automated sampling and tandem Agilent 5975 Mass Selective Detector and peak analysis with the Chemistation data system. LC-MS/MS QTOF analysis was performed with UPLC Waters I Class and tandem MS/MS Xevo G2S QTOF with UNIFI software. GC-MS analysis identified five compounds with a quality match of 90% and above, namely 3-pentadecylphenol (31.68%), 5,5’-(oxybis(methylene)]-bis-2-furancarboxy-aldehyde (5.67%), 5-(hydroxymethyl)-2-furancarboxy-aldehyde (23.51%), 4H-pyran-4-one, 2,3-dihydro-3,5-dihydro-6-methyl (5.00%), and n-hexadecanoic acid (4.71%). Five major compounds were identified for the first time in B. macrophylla fruit juice by LC-MS/MS analysis, i.e., (E)-hexadecyl-ferulate, digupigan A, eburicoic acid, hydroginkgolinic acid, and terminalic acid. The health benefit of some of these detected phytochemicals supports the use of juice as the main ingredient for functional food.","PeriodicalId":127127,"journal":{"name":"International Journal of Biological, Physical and Chemical Studies","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127039742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiple industrial operations near the area make it susceptible to pollution, thereby affecting the aquatic organisms and the people who depend on the bay for food and livelihood. Thus, the main objective of the study was to determine the Mercury (Hg), Lead (Pb), and Nickel (Ni) concentration in the flesh of Marsh clam (Polymesoda expansa) in different mangroves wetlands across Butuan Bay. Heavy metal concentration was assessed using cold vapor atomic absorption spectroscopy for Hg and Atomic Absorption Spectrophotometry for Pb and Ni. The results revealed that Hg and Pb concentrations were below the detection limits (BDL), while Ni concentrations were within the tolerable limits established for bivalves. Human health risk via the consumption of P. expansa was calculated using the estimated daily intake (EDI) and Target Quotient Hazard (THQ). Results show that the EDI of Ni exceeded the oral reference dose, but its THQ was below the standard THQ value. In conclusion, the consumption of P. expansa does not pose any adverse health effects on human health. Still, further investigation and monitoring of the mangrove ecosystems are encouraged to secure the environment's health and the communities that depend on it.","PeriodicalId":127127,"journal":{"name":"International Journal of Biological, Physical and Chemical Studies","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133982950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Single target colonies were sub cultured, and identification was based on culture, morphology, and biochemical characteristics. Enterococci isolates were subjected to biofilm assay (Tube method), and resistance pattern was determined for both biofilm-formers and non-biofilm-formers. Genomic DNA was extracted using the Bioneer kit, and the gene for virulence was detected by PCR and agarose gel electrophoresis. 148 Patients having one or more urinary symptoms were the study population. The aim of the study was to determine the multidrug resistant ability of biofilm-forming Enterococci. A number of growths were encountered; Enterococci accounted for only 9.46% (14), the highest prevalence was seen in the age group 21-30 (35.71%), and females (64.29%) were more prone to enterococcal infection than their males (35.71) counterpart. There is a relationship between biofilm production and antibiotic resistance because multidrug resistant Enterococci isolate produced bands against esp gene with an average of 510kbp. Biofilm forming strains showed the highest resistance to gentamicin and penicillin (83.3%), and vancomycin can be considered a good alternative therapy in enterococcal UTIs because of its lower resistance (75%).","PeriodicalId":127127,"journal":{"name":"International Journal of Biological, Physical and Chemical Studies","volume":"105 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132999605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The catalysts used were Na-bentonite and Limestone NTT which were first analyzed using XRF, XRD, and SEM. Saponification pretreatment was carried out on CPO to facilitate the cracking process using a catalyst. The saponification product in the form of a mixture of soap and glycerol was then analyzed by DSC to determine the degradation temperature. Catalytic cracking is carried out in two stages, namely, the first stage hydrocracking at a temperature of 250-350°C using a stainless steel reactor is the source of catalyst Fe / Cr. The resulting distillate was then cracked again using a Na-bentonite catalyst and a TKNTT catalyst. The resulting fuel is a hydrocarbon fuel which is confirmed from the FT-IR results which indicate the presence of long-chain hydrocarbon compounds. This data is also supported by the results of the GC-MS analysis which shows that the fuel fraction produced is mostly biogasoline. Where cracking using a Na-bentonite catalyst produces a biogasoline fraction of 61.36% and a biodiesel fraction of 38.63%, THAT produces a biogasoline fraction of 88.88% and a biodiesel fraction of 11.11%. The characteristics of the hydrocarbon fuels that have been analyzed show that the calorific value of combustion is 6101 cal/g which is determined using a bomb calorimeter, and the cetane index is 62 which is analyzed using CCI. Both types of hydrocarbon fuels have met the physical requirements that must be possessed by biogasoline fuel based on SNI standards.","PeriodicalId":127127,"journal":{"name":"International Journal of Biological, Physical and Chemical Studies","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122880748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetic moment values of the complexes showed that both Mn (II) and Co (II) are paramagnetic. The spectroscopic data of metal complexes indicated that the metal ions are complexed with azomethine nitrogen and deprotonated oxygen atom. Corrosion inhibition of the schiff base and Mn (II) and Co (II) complexes were evaluated using the weight loss method in a 0.1MHCl solution for copper metal. The inhibition efficiency increased with increasing inhibitors concentration. The negative values of Gibb’s free energy of adsorption (ΔGads) confirmed the spontaneity and physical adsorption of the inhibition process which is inconsistent with Langmuir adsorption isotherm.","PeriodicalId":127127,"journal":{"name":"International Journal of Biological, Physical and Chemical Studies","volume":"207 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121185845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
